Patent GB-147693-A (GB)
Title: An improved carburetter
IPC: F02M19/035
Filed: 1920-07-08
Abstract: 147,693. Genety, L. Jan. 9, 1919, [Convention date]. Spray carburettors. - The ratio of air to fuel is maintained at a desired value by modifying the air pressure existing at the jet orifice J bv means of a baffle P. The baffle is practically perpendicular to the air flow, is not necessarily flat, and serves to increase the pressure at the jet orifice. Specifications 10115/13, 2670/14, 22657/09, and 128,284 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also means for providing a slight excess of fuel when accelerating such means comprising an airtight chamber C communicating with the induction passage A on the engine side of the throttle valve B through a tube T open to the atmosphere at S<1>. The level of fuel in the chamber C during normal running is at N<2>. Upon closing the throttle valve B, the suction at S and therefore in the chamber C increases, causing the fuel to rise as at N', thus providing an additional head of fuel to give an augmented supply when the valve B is again opened. This arrangement compensates for the difference in inertia of the fuel and air which usually produces a lag in the fuel supply. This subject-matter does not appear in the Specification as accepted.

Filed: 1939-07-13
Abstract: 531,153. Measures of length. STEVENS, A. H. (Keuffel & Esser Co.). July 13, 1939, No. 20447. [Class 106 (ii)] A metal tape or rule has raised graduations formed in the metal and depressions therebetween containing a pigmented colouring material. A flat strip 20 of metal is cleaned and then subjected to, for instance, an electrolytic treatment to apply a thin coating 22 of black nickel on both faces and edges. One surface 24 is then marked by printing thereon an etch-resisting covering for the background leaving numerals 6, graduations 4 &c. uncovered. The strip is next passed through an etching bath and the black coating removed from those portions not covered by the resistant followed by the removal of the metal itself in the unprotected areas. On removal from the bath the strip is passed through a bath to neutralize and wash away the etching solution. The strip is now treated with rust preventing agents and treated with a solution of an artificial condensation product suitably pigmented and the solution removed before drying from the upstanding portions by a scraper leaving the graduations &c. pigmented. The strip may now be covered with a clear cellulose lacquer. Instead of applying the black nickel, the resistant material may be applied to the untreated tape. In this case, the background will be the ordinary metal surface. In a modification, the graduations &c. may be elevated and the background depressed. In the first case, the background is black with coloured numerals &c. and in the second the background is coloured and the numerals &c. black. In the latter case the background does not extend to the edges of the tape, but ridges are left. In both cases, the numerals &c. graduations do not extend right across the strip. Instead of etching, the strip might be pressed or moulded or patterned layers may be applied electrolytically, or metal may be sprayed on through a mask to produce the raised areas.

A shaker moulding machine has means for successively filling and compacting the sand in a mould flask 4, in the form of a sand frame 5 and a jolting frame 21 which are independently positioned on the flask by known hoisting means. The sand frame 5, which has a vertically displaceable sprue pattern 7 attached thereto, is positioned on the flask, the sprue pattern 7 being adapted to contact the casting pattern 3 just prior to the seating of the frame 5 on the flask. The flask is filled with sand and preliminary shaking is effected by the shaker device 2. The sand frame is then removed and the jolting frame with sprue pattern 15 is located on the flask. The second sprue pattern 15, which is vertically displaceable, enters the sprue cavity formed by the first sprue pattern 7. The sand is now finally compacted by the jolting weights 23, 24, the weight 24 forming a pouring basin around the sprue pattern 15. The operation of the hoist raises the sprue pattern 15 before the jolting weights.
